Publication number: 20240172920Abstract: An endoscope device includes an imaging device, a determination unit, and a control unit. The determination unit is configured to determine the position and the size of a region including the distal end of a treatment tool seen in an image. The control unit is configured to set a control region in the image based on the position and the size. The control unit is configured to execute exposure control of controlling brightness of the image by using a value of a pixel in the control region. The control unit is configured to display the control region on a display. The control region includes a first region and excludes a second region. The distal end is seen in the first region. Abase end of the treatment tool is seen in the second region. The second region is in contact with a boundary of the image.Type: ApplicationFiled: October 31, 2023Publication date: May 30, 2024Applicant: Evident CorporationInventor: Hideyoshi YAMAUCHI

Publication number: 20230009448Abstract: An inspection analysis method includes an analysis step, a prediction step, and an output step. A processor analyzes inspection information related to an operation in an inspection and generates first operation data and second operation data indicating a content of the operation in the analysis step. The first operation data indicate a content of the operation in a first inspection. The second operation data indicate a content of the operation in a second inspection performed after the first inspection is completed. The processor compares the first operation data and the second operation data with each other and predicts a state of an inspection target in the prediction step. The processor outputs state information indicating the state to a reporting device in the output step.Type: ApplicationFiled: July 5, 2022Publication date: January 12, 2023Applicant: Evident CorporationInventor: Hideyoshi YAMAUCHI

Patent number: 7850598Abstract: A CPU includes: an original image recording function for recording a still image or a recorded image as an original image; a contrast correction function for performing contrast correction on a still image or a recorded image; a coordinate calculation function for calculating pixel coordinates on an original image which correspond to pixel coordinates designated on a contrast corrected image; a stereo measurement function for performing stereo measurement using pixel coordinates of an original image calculated by the coordinate calculation function; a measurement result reflection function for reflecting on a contrast corrected image a measurement result of stereo measurement performed by the stereo measurement function; and a dynamic range expansion function for enhancing brightness of an image area which is darker than a predetermined threshold. These functions enable stereo measurement to be performed precisely using an image on which image processing has been performed.Type: GrantFiled: December 21, 2005Date of Patent: December 14, 2010Assignee: Olympus CorporationInventors: Eiichi Kobayashi, Hideyoshi Yamauchi
